"You have to," he answered. "But I think she seems a lot more focused now than she was five, six months ago."

Sheen continued: "There is a reason that I root for [her], because we fell in love with this little girl that was just an absolute genius and had this great light about her, and that's still there. You can't extinguish that.

"I root for her because when you're that talented, it just doesn't go away. Sometimes your appetites get in the way."

The Anger Management actor added that he continues to reach out to Lohan because he can sympathize with her struggles.
